This should help insure that jobs are not prevented from running
at the same time on the same node due to memory limits.

when acct_policy_job_runnable_post_select() is call for job without
job_resrcs (eg.: from _attempt_backfill() or when select_nodes() can't
find free recource) but with req_node_bitmap.

This patch will change reason of jobs like in test 21.39 from
"JobState=PENDING Reason=QOSGrpNodeLimit" to
"JobState=PENDING Reason=Resources"

bug 6675

Promote two functions in opt.c to extern, and rename the entry point
to the translation code to xlate_batch_script().

Unused by launch/slurm.

Only works with non-launch/slurm plugins.

There is only launch/slurm currently.

Hasn't been documented since at least version 2.6, and does nothing.

Changed to the documented form before 17.11 was released.

Return an xmalloc()'d string. Clean up string handling to
use xstrfmtcat / xstrcat / snprintf instead of sprintf.

Use that new function in a minimal new cpu_freq_set_env().

No new functionality, just for clarity and consistency.

Can now only be used to launch steps in an existing job allocation;
it can no longer be used by SlurmUser to create a new job allocation
with a given jobid value.

Bug 6691.

Bug 6691.

If running within salloc or a job step, both SLURM_JOB_ID and SLURM_JOBID
would be set to the same value, and SLURM_JOB_ID would overwrite SLURM_JOBID
as it is parsed second.

The only time this would cause a difference in behavior is if SLURM_JOBID
were set, and SLURM_JOB_ID were not. Which is not something that can be
caused by Slurm itself.

This configuration previously caused test15.10 to fail
(but only when run as part of full regression test due
to NHC running on previous jobs).

Non-operators are not permitted to submit jobs with a negative
nice value. Rather than silently reset the value, reject it outright.

Without moving the function, it is undefined when referenced
